# Using tar 1.15.x the following equivalent command sets:
#
# 1. tar cf archive file1 file2
# and
# 2. tar cfT archive /dev/null
# tar rf archive file1
# tar rt archive file2
#
# produced different archives (GNU format is assumed). Namely, in the
# second case the mode field of all members, except the first, was truncated
# to lower 3 octets (& 0777).
